The first 2-5 years from the onset of psychosis is regarded as the critical period to improve the prognosis, so the intervention including more recent-onset psychotic patients might be of use. With regard to a setting of the psychoeducational intervention, a homogeneous group one can make the program better fitted for their problems. The present study aims to examine if the strength-based family psychoeducaiton for youth psychosis in a group setting in addition to the treatment as usual would be more effective for alleviating the psychological distresses of the family than the treatment as usual alone. Moreover, its impact on the family of recent-onset psychosis is explored as the subgroup.
